Construction Concrete and Aggregate Testing

Concrete and aggregate testing from SGS – helps you ensure that the quality of your concrete and aggregate complies with compulsory regulations and quality control standards.

Concrete and aggregate used in your construction projects has to meet strict regulations and quality standards. As these standards are often compulsory, concrete and aggregate testing by an independent third-party is necessary to help assure compliance. Our full range of independent concrete and aggregate testing services can help ensure both the quality of your concrete and the quality of your aggregate.

Why use concrete and aggregate testing from SGS?

As an independent third-party, we provide you with highly specialized personnel, technology and testing laboratories, along with accreditation for a wide range of national and international standards. We can help you:

Comply with the relevant regulations and quality standards

Make informed decisions with advice, guidance and review of test data

Get the testing you need with bespoke test procedures when standard testing does not suit

Ensure the quality of concrete

Ensure the quality of aggregate

Evaluate the performance of available materials

Control concrete quality during – and after – construction

Comprehensive concrete testing for your project

We offer you comprehensive concrete testing at every stage of your project. From on-site slump testing as you pour your concrete, through to testing hardened samples for physical characteristics in our laboratories, our concrete testing includes:

Sampling of fresh concrete and slump testing on site

Making and curing test specimens on your site and in our laboratory

Compression and flexural testing

Compression tests on molded specimens and on hardened concrete cores

Mass per unit volume testing for hardened concrete

Securing and testing cores from hardened concrete

Flexural strength and toughness of hardened concrete

Testing for the compressive strength per unit mass of grout

Water absorption and permeable voids testing

Apparent volume testing

A full range of aggregate testing at every stage of your project

We offer you broad aggregate testing at every phase of your project. From our on-site quality control monitoring when you source the aggregate, right through to physical characterization in our specialized laboratories, our services include testing for:

Bulk density

Polished aggregate friction value

Particle density and water absorption

Sieve analysis

Material finer than 75 ìm\

Particle shape

Flakiness index

Angularity number

Fine particle size distribution

Aggregate crushing value

Wet/dry strength variation

Los Angeles Value

Soundness

Weak particles

Clay and fine silt

Organic impurities other than sugar

Resistance to stripping

Color of aggregate

Average least dimension

Resistance to wear by attrition

Unconfined compressive strength
